Your analysis is flawed (on many levels...).
China put some serious measures in place, and they seem to have the virus under control. Yet, when everything in China gets back to normal because the restrictions are lifted, experts have stated that the virus is likely to start up again, at least in pockets.
Korea has done serious and sensible measures; nobody's liberty has been affected, people are still having pleasant lives, but hospitals and GPs are restricted, everyone is wearing masks to slow down the spread and help the health services, individual cases (i.e. where the people visited, with address) has been shared with local populations so that good decisions can be made - for example, I avoided the Burger King for two weeks that an infected person had visited the same day they were admitted to a hospital.
As can be seen from the photo 'Arry posted, above, the Americans are doing sweet FA to slow down the spread of this virus and as a result the US numbers will be in the hundreds of thousands very quickly and their health service will be over-loaded within 2 months. Europe appears to be equally ill prepared.
You see the high mortality rate in Italy? Well wait until this virus hits the mega-obese communities in the US... This has already stated by experts, yet the American/European governments are not taking the same actions as the Chinese/Korean governments. Korea has really been quite 'gentle' restrictions, Europe/US could certainly do the same without affecting people's civil liberties. Alas, we see in the picture above and comments on this thread such as "just leave it to run its course, no actions/restrictions are required" that the civil liberties that many folks invoke are being dumb in a way that negatively affects society.
